Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).

Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions
Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.Abstract The surface of Mercury contains elevated amounts of sulfur of up to 4 wt.%. Volcanic degassing of S from the interior of the planet could have initiated sulfidation reactions between the degassed S and surface materials in the planet's past, leading to the observed surface S enrichment.

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract La Soufri'ere de Guadeloupe is an active volcano of the Lesser Antilles Volcanic Arc. Its last eruption halted in 1977, yet hydrothermal activity has increased over recent years, raising summit instability hazards. The link between hydrothermal fluids and detachment landslide surfaces is well established and exacerbated by inflation ...

Symbiont‐Mediated Molybdenum Cycling Shapes Coral Skeletal Mo Isotopes
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Coral skeletal trace‐metal compositions are commonly assumed to derive from seawater, yet the extent to which biological processes contribute remains poorly constrained. Here we present the first paired Mo isotope measurements of coral tissue, symbiotic zooxanthellae, and skeleton.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Water plays a critical role in Earth's mantle dynamics and evolution, yet lower‐mantle storage mechanisms remain debated. δ‐AlOOH and SiO2 phases have been independently proposed as high‐pressure water hosts. Here, we conducted in situ synchrotron X‐ray diffraction experiments with a multi‐anvil apparatus and sintered diamond anvils to ...

Quantifying the Effects of Nickel on Earth’s Inner‐Core Nucleation
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The formation of Earth’s solid inner core marks a major transition in the thermal and chemical evolution of the deep Earth, yet its origin remains paradoxical, as initial nucleation appears to require unrealistically large undercooling in the outer core.

(ICA) in Endmember Extraction and Abundance
, 2005 —Independent component analysis (ICA) has shown success in many applications. This paper investigates a new application of the ICA in endmember extraction and abundance quantification for hyperspectral imagery. An endmember is generally referred to as an

A novel approach for endmember bundle extraction using spectral space splitting [PDF]
, 2015 The traditional endmember extraction methods search for a fixed set of endmembers, each one assigned to a single material. However, in many real applications, the materials of interest may present spectral variability which is related to subtle ...

Real-Time Simplex Growing Algorithms for Hyperspectral Endmember Extraction
, 2010 The simplex growing algorithm (SGA) was recently developed as an alternative to the N-finder algorithm (N-FINDR) and shown to be a promising endmember extraction technique.
